Lactate dehydrogenase isoenzyme patterns of rat testis and reproductive tract: changes during postnatal development

ABSTRACT

Electrophoretic patterns of LDH isoenzymes in whole testis as well as in testicular isolated cells of immature and mature rat are demonstrated. Further, these molecular forms are studied in testis, vas deferens, epididymis, seminal vesicle, prostate and during development from one week to 4 weeks and above at selected time intervals. LDH - X is demonstrated only in testis and cells found in seminiferous tubular compartment and is suggested to appear during the prophase of frist meiotic divison of spermatogenesis. The isoenzymes appear to be intense during 2 - 3 week of age and do not show any significant shift as the development progresses
